Value Collection 581472P Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 581472P is a hex socket cap screw designed for high-strength fastening applications. It features a 3/8-16 UNC thread size and measures 3-3/4 inches in length under the head. The 5/16-inch hex drive allows installation with a standard Allen or hex key. Constructed from alloy steel with a black oxide finish, it resists corrosion and surface wear under typical service conditions. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for mechanical assemblies that require reliable clamping force. It is partially threaded along the shank.

This screw is used across a wide range of industrial, mechanical, and trade applications where a recessed-drive, high-strength fastener is required. Common installations include machinery frames, brackets, jigs, HVAC equipment housings, electrical enclosures, and structural assemblies. The black oxide finish suits both interior and moderate-exposure environments. Licensed tradespeople and maintenance technicians working in manufacturing, mechanical contracting, and facility maintenance will encounter this fastener type regularly.

Key Features

• 3/8-16 UNC thread size for broad compatibility with standard tapped holes
• 3-3/4 inches length under head suits deeper grip applications
• 5/16-inch hex socket drive for use with Allen keys or hex bit drivers
• Partially threaded shank provides a clamping zone free of thread engagement
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide coating reduces surface corrosion and glare in finished assemblies

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw conforming to ASME/ANSI B18.3, compatible with any tapped or threaded hole machined to 3/8-16 UNC specifications.

Installation Notes

Install using a 5/16-inch hex key or socket bit driver. Ensure the mating tapped hole is clean and free of debris before threading. Always torque fasteners to the assembly manufacturer's specification — do not use impact drivers at full power on socket cap screws without a torque-limiting setting. Black oxide does not provide heavy corrosion protection; apply a light oil or thread lubricant in high-moisture environments.
